OLIVER E. GOODELL, OF BANGOR, MICHIGAN.

PLOW-CARRIAG E.

SPECIFICATION forming part of Letters'Patent No. 237,010, dated January25, 1881.

Application filed April 1, 1879.

To all whom it may concern Be it known that I, OLIVER E. GooDELL, ofBangor, in the county of Van Buren and State of Michigan, have inventedan Improvement in Plow-Uarriages, of which the following is aspecification.

The nature of this invention relates to certain new and usefulimprovements in the construction of carriages for supporting andoperating plows.

The invention consists in the peculiar construction, arrangement, andcombination of certain devices for regulating the pitch of the plow, allas more fully hereinafter set forth.

In the drawings, Figure 1 is a perspective view. Fig. 2 is an enlargedperspective of the device for raising and lowering the wheels.

In the accompanying drawings, which form a part of this specification, Arepresents a suitable frame, in the downwardly-projecting ends of whichare journaled the crank-shafts or axles B B, whichcarry thetraction-wheels O.

D is a'supplemental frame connected to the frame A by means of' the bentarms E.

F are ratchet-bars securing the, two frames A D together at their tops,and with which engage the levers G, the lower ends of which are securedto a ratchet-faced block, H, which engages with a similar block, I,secured to the crank-shaft, as shown, and by means of which the saidshafts are raised or lowered by the operation of the levers G. Bysecuring the levers to ratchet-blocks their position in relation to thecranks can be changed, and they can be adjusted to move the cranks moreor less in either direction, as desired.

The tongue P is 'remo'vably secured in the frames, as shown. An -iron orrod, R, is vertically adj ustably secured to the side of the tongue bymeans of an eyebolt and washer, 0, and serves as a stop to prevent thepoint of the plow from flying out of the ground upon coming to anobstruction.

J is an adjustable bail, one end of which is pivoted in the frame A by abolt, to, which passes through both bars of the frame and the bail,while the opposite end passes through the opposite side of the frame,being pivoted in the same at b, and terminating in an arm, K.

The short arm of a bell-crank lever, L, pivoted upon the side of thetongue, is pivoted to the free end of the arm K by a link, N, and bythese means the plow, which is secured to the bail by means of a clamp,O, as shown, is raised or lowered, as may be desired.

The bail, arranged as shown in the accompanying drawings, is adjustedfor the operation of a right-hand plow, and in order to operate aleft-hand plow the bail should be reversed and the tongue shifted to theleft. By this construction the lever which operates the parts lastdescribed is always between the horses, and avoids injury to the lattershould they fly back.

What I claim as my invention is In a plow-carriage, the bail J,reversibly secured within the frame A, substantially as described, incombination with the lever L, arm K, and link N, as and for the purposesset forth and shown.
